Abstract

Various embodiments and methods relating to an optical device (20, 120, 220, 320, 420) in which light is attenuated in a first layer (122) dependent on the angle of incidence and in which gain is applied to light by a second, reflective layer. Between the first and the second layer a modulator (124) may be disposed.
